Systematic Quantitative Characterization of Surface Nanostructures

Al-Mousa A., Niemann D.L., Gunther N.G., Rahman M., Santa Clara University / PDF Solutions, US

In this paper, a systematic analysis technique is presented and applied to Atomic Force Microscopy (AFM) data. Our technique isolates surface nanostructures and extracts quantitative information such as their shape and size. Examples of features [...]

Characterization of Silane Nanoadhesion by means of Dynamic Force Spectroscopy

Ptak A., Makowski M., Niemier M., Cichomski M., Gojzewski H., Czajka R., Poznan University of Technology, PL

Using a modified atomic force microscope the nanoadhesion between a silicon tip and a monolayer of 1H, 1H, 2H, 2H-perfluorodecyl-trichlorosilane was measured at different loading rates. Adhesion force-versus-loading rate curves could be fitted with two [...]

Environmental Digital Pulsed Force Mode AFM in Biomedical Coatings Research

Haugstad G., Wormuth K., University of Minnesota, US

We report ongoing methodological developments using Digital Pulsed Force Mode AFM of model coatings containing the drug dexamethasone dispersed in polylactide (biodegradable), poly(butylmethacrylate) (PBMA), and PBMA/poly(laurel methacrylate) (PLMA) blends. Studies include (1) multi-technique analyses, understanding [...]

Influence of Al-Doping on the Optical Properties of ZnO films

Ma S.Y., Chen H.X., Glass J.T., Parker C.B., Northwest Normal University, CN

Al doped ZnO (AZO) thin films were deposited on glass substrates using the radio frequency reactive magnetron sputtering technique. The effect of Al concentration on the microstructure and the luminescence properties of the AZO thin [...]

Organic Solvent Dispersed TiO2 Nanocrystal Sol: Synthesis and Characterization

Rao Y.Q., Antalek B., Minter J., Mourey T., Blanton T., Slater G., Slater L., Slater G., Slater L., Fornalik J., Eastman Kodak Company, US

Anatase TiO2 nanocrystals with a mean diameter of about 10 nm were successfully synthesized through a non-aqueous sol gel route without the use of air free equipments. The nanocrystals were well dispersed in organic solvents [...]

TiO2 Nanoparticles Mixed MEH-PPV Hybrid Absorbing Layer

Verma D., Dutta V., Indian Institute of Technology Delhi, IN

Conducting polymers/inorganic semiconductor nanoparticles composite are attracting attention due to their tunable optical and electrical properties. The properties of the hybrid layer processed from the blend solution depend on the degree of dispersion of nanoparticles [...]

Physical Properties of Metal Coated Polymer Particles for Anisotropic Conductive Adhesive

Zhang Z.L., He J.Y., Kristiansen H., Norwegian University of Science and Technology, NO

Metalized and monodisperse polymer particles with diameter ranging from 0.5 to 30 µm are increasingly used in developing new electrical packaging technology, such as Anisotropic Conductive Adhesives (ACA) in Flat Panel Displays (FPDs). In these [...]

Use of Nanofilters for the Control of Polution from the Industrial Chimneys

Agarwal R., Katiyar V.K., Tewari P., Indian Institute of Technology, IN

The objective of this study is to elaborate the use of nano filters for controlling the pollution of the industries coming out of the chimneys. The nano filters allow small gaseous molecules to pass trough [...]

Fabrications of Bifunctional Janus and Triblock Saturn Colloids

Lin C.C., Ho C.-C., Chang C-C, Kuo C., National Cheng Kung University, TW

A synthetic approach for the fabrications of Janus and Saturn colloids was demonstrated by the sequential embedment and surface modification of silica colloids. Electrospinning of poly(methyl methacrylate) (PMMA) and poly(4-vinyl pyridine) (P4VP) blends produced polymer [...]

Pulsed laser co-deposition of titania with Fe: chemistry, local atomic structure, and light-dependent magnetic properties

Negrila C., Logofatu C., Socol G., Macovei D., Teodorescu C.-M., National Institute of Materials Physics, RO

Transition metal doped titania has been revealed as a promising diluted magnetic semiconductor. We report the synthesis of TiO2:Fe and of mixed Ti and Fe oxides by pulsed laser deposition. The obtained layers were analyzed [...]
